✦ Synopsis

The predlctlon of multicomponent distdlation efficiencies from binary data IS lnghly desirable as it IS physically impossible to perform the experlmental study of all the systems of Industrial importance In the present work a new method of predicting ternary efficiencies H presented The vahdity of the method IS assessed comparmg expertmental ternary distdlation lines with predicted distillation lines Experimental results obtained m a 38 mm diameter seven plate sieve plate column with the binary systems cyclohexaneln-heptane, cyclohexane/toluene and n-heptaneltoluene and the ternary system cyclohexane/n-heptaneltoluene are used for such comparison Experimental results obtained with the ternary system show the existence of Murphree efficlencles greater than unity for the Intermediate component Such mterestmg physlcal sltuatlons are also predlcted usmg the new method

## Abstract A first approximation to the multicomponent plate‐efficiency problem has been carried out with a film model combined with equations for steady state diffusion in a ternary gas mixture. Numerical integration of the equations through a plate yields the ternary efficiencies as functions of
